"After a few more restrained recent outings, MB&F has returned to outer space with the Horological Machine No. 9 (HM9). Reminiscent of the HM4 “Thunderbolt” and arguably the coolest Horological Machine to date, the HM9 is a sleek, sculptural timepiece powered by a delta-shaped form movement. But the movement is also one of the most complicated to be found in a Horological Machine, not merely because of its form but the fact that it’s regulated by twin balance wheels linked by a differential.

Like many of MB&F’s other Horological Machines, the HM9 is a driver’s watch, with the time shown on a vertical face, allowing the watch to be read with one’s hands on a steering wheel. But more importantly it is an artful blend of the twin philosophies that shape each of MB&F’s model lines. While the form and style is vintage Horological Machine, the movement takes inspiration from the Legacy Machine 2 (LM2)."
